UniMeasure products, as represented by Measurement & Control Solutions, manufacture a broad line of wire rope actuated linear position and linear velocity transducers.
UniMeasure manufactures a broad line of wire rope actuated linear position and linear velocity transducers as well as analog output rotary position transducers. In addition, UniMeasure offers a selection of digital panel meters that interface easily with all UniMeasure transducers.
Often referred to as string pot, yo-yo pot, draw wire transducer, cable extension transducer, cable actuated transducer, UniMeasure extending wire rope linear position transducers have proven to be an attractive approach for a multitude of applications in many different industries. With relatively non-critical alignment requirements, compact size, and ease of installation wire rope actuated transducers are the linear position measurement system of choice in applications as diverse as bone densitometers in the medical industry, crash testing in the automobile industry, pump jacks in the crude oil extraction industry and irrigation and flood control in the water management industry. With a wide variety of electrical outputs, UniMeasure linear displacement measuring products provide an extremely cost effective method for linear position feedback.
UniMeasure rotary position transducers provide an analog output signal that is directly proportional to the angle of rotation of the shaft of the device. With a voltage or 4 to 20 mA analog electrical output, UniMeasure rotary position transducers are also known as angle sensors, analog rotary shaft encoders and analog multiturn analog shaft encoders and absolute angle encoders. These devices are commonly used in applications where an absolute output signal is a must. Typical use occurs in closed loop process control and in testing applications where oscillatory rotary motion occurs. UniMeasure absolute analog rotary position transducers have proven to be an extremely cost effective alternative for measuring rotational positioning.

With the transducer mounted at a fixed position, the extensible wire rope is attached to a moveable object. As movement occurs, the extension of the wire rope rotates an internal capstan and sensing device to produce an electrical output signal proportional to the wire rope extension and/or velocity. An internal torsion spring maintains tension on the wire rope and serves as the retraction mechanism. The sensing device may be a precision potentiometer, digital encoder or, for velocity measurement, a tachometer.
UniMeasure linear position transducers have been used as feedback devices in a large variety of applications in many different industries. A few of the many application areas are listed below.
